Negative electrode for lithium secondary battery, method for manufacturing same, and lithium secondary battery comprising same

The present invention relates to a negative electrode for a lithium secondary battery, a method for manufacturing the same, and a lithium secondary battery comprising the same. More specifically, in the negative electrode, a salt coating layer containing a lithium salt and an additive is formed between a plurality of lithium thin films so that the salt coating layer dissolves during operation of the battery and can replenish the lithium salt and the additive consumed in the electrolyte, and thus life characteristics of the battery can be improved while maintaining high coulombic efficiency. 本发明涉及锂二次电池用负极、其制造方法以及包含其的锂二次电池。更具体地，在所述负极中，在多个锂薄膜之间形成含有锂盐和添加剂的盐涂层，使得所述盐涂层在电池运行期间溶解并且能够补充电解质中消耗的锂盐和添加剂，因此可以在保持高库仑效率的同时改善电池的寿命特性。
